The underlining is correct. The variable input is undefined in your
program. Since it is undefined, the compiler has no way to know what it
is. Changing it to HI won't fix it either. You have to change it to
hi. Java is a case sensitive language. HI is undefined, hi is defined.
If you hover over the underlined input, you will get a popup indicating
the error. This will help you figure out these errors on your own
without having to wait for a response on a mailing list.
